PACKING- DEVICE FOR FILLED-CAN-CLOSING MACHINES.

Application filed July at, 1925. Serial No. 45,886.

The in vontion relates to new and useful improvementsin packing devicesfor filled can closing machines and more particularly to a packingdevice which is positively operated and which cooperates with the filledcan while the filled can is moving into the closing machine.

An object of the invention is to provide a packing device wherein theoverflowing pad is positively moved into cooperative relation with themoving can and is positively maintained in horizontal positionthroughout the entire movement thereof.

A further object of the invention is to provide a packing device of theabove type wherein the overflowing pad is mounted on a positivelyrotated support and is maintained in horizontal position by a similarpositively rotated support set eccentrically to the firstnamed supportand carrying a pin cooperating with a crank arm mounted on the shaftcarrying the pad so that as the two supports are rotated one supportpositively rotates the pad into cooperative relation with the can whilethe other support maintains the pad in horizontal position. 1

These and other objects will in part be obvious, and will in part behereinafter more fully disclosed. v

In the drawings which show by way of illustration one embodiment of theinvention Figure 1 is a view partly in front elevation and partly insection, showing a portion of a filled can closing machine having myimprovement applied thereto, I r

Fig. 2 is a sectional view on the line 22 of Fig. 1.

Fig. 3 is a sectional view through the casing for the rotating membersand showing the manner of positively rotating one member from the other.

Fig. 4 is a sectional view on the line -ld of Fig. 2.

The invention is directed broadly to a packing device for a filled canclosing machine, that is, a machine wherein open ended cans after theyare filled are closed by the seaming of the top end to the body portionof the can.

Prior to my invention it has been common to provide a closing machinewith a rotating drum having a thread wound thereon, which drum becomes afeeding mechanism for feeding the filled cans to the machine where theyare closed. The thread on this drum slides the cans one after anotheralong a horizontal stationary support. Located above this sup? port forthe Cans is a packing device which includes a pad adapted to move downonto the filled can for the purpose of depressing any floating fruit orvegetables down into the can, and thus properly overflowing the can sothat it is in condition to be closed with a minimum amount of spill. y

The present invention is directed particularly to the means ofsupporting and operating this overflowing pad.

This means includes a rotating disk or traveling member in'which thesupporting shaft for the pad is mounted and on .the rear end of saidshaft is a depending arm. Located in the rear of the supporting disk isanother traveling disk having a stud adapted to engage the free end ofthe crank arm. This last-named disk is positively rotated and becomesthe driving disk for actuating the pad. There is a counter-shaft whichconnects the two disks together so that one rotates the other.

Referring more in detail to the drawings, the machine includes a mainframe 1 on which is adjustably mounted a table or bracket 2. Carried bythis table 2 is a shaft 3, which is mounted in suitable bearingssupported on the table. Mounted on this shaft 3 is a drum 4, having aspirally wound thread 5. Associated with the drum 4 is horizontalsupport 6, and the can which is indicated at C in the drawings rests inpart upon this horizontal support 6 and in part on the drum 4: and ismoved along continuously by the thread on the drum. Thus it is the cansare delivered one after the other onto a support 7 which cooperates withthe closing mechanism, wherein the end is seamed onto the can body. Asthe cans are moved along the sup port therefor, an overflowing pad 8 ismoved down into cooperative relation with the filled. can so that anyfloating contents in the can is pressed down into the liquid content ofthe can, thus causing an overflowing if the can is too full.

The pad works in a well known way and the invention is directed moreparticularly to a means for actuating the pad. There is only one pad inthe machine. This pad is secured to a short shaft 9 by means of clampingscrews 10-10 which clamp the sleeve of the pad onto the end of theshaft. The mechavi, r

nism for supporting and operating the pad is carried by a casing. 11.which is formed a part. of the bracket 12 secured to the machineby'suitable means 13-13, see Fig. 1.

Located in'this: casing 1:1; is arotated sup-V, port 1.4 Which as shownin. the. drawings is in the form of a gear Wheel. This gear or supportis mounted on short stub shaft I5 which is in turn mounted in the casing11. Secured to the, rear side of the support or gear-l4 is a V sprocketWheel 16. This sprocket Wheel is driven by a sprocket chain 17wl1ichruns over .a sprocket heel 18 on a short shaft 19 car ried in a housing20', wh ch is securedto the table Qsupporting thedruin; This shaft 19'also carries asprocket wheel 21 and asproeket 7 chain 22 runs over thissprocket Wheel 21 and also over a sprocket wheel on the cross shaft 23.The cross shaft 23 carries a beveled gear 24 which meshes with a beveledgear 25 on thee'nd of" the shaft The cross shaft 23 therefore becomes acommon driving means for the drum lz'and for the pad actuatingmechanism. It is by this means that the pad is driven in proper" t'imingwith the drum.

The gear 14 meshes with a gear 26 carried by a cross shaft 27 I mountedin suitable bearings in the casing 11. This cross shaft carries a gear28' which is of'the same diameter as the gear 26; V I

The shaft 9 carrying the packing pad is 'mounted in a rotatable disk orsupport 30' as the same timing. and have a'one-to-one mo ti on; r l

On the end of" the shaft- 9 there is a de pending crank 321' Thisdepending crank is rigidly connectedto the shaft 9; Mounted on thegear'or support 145 is a stud 33. This stud carries a' rectangular block3 lrwliich is free to urn on the stud. There'ctangular block 34 is located inthegforked end 35 of the crank 3211 his the-support 30 r(--tates, t-he shaft 9' will bodily travel about the center of the supportand this \villlfgive the pad a bodily iZl'TEl'VGl in air uprightcircular path. The timing ofthis p ad issuch that the pad will move downinto proper cooperative relation with the can.

her on the under face thereof which is'o f substantially the samediameter as the can, and this pro ecting portion mov ng intothe can willdepress the floating contents of the can 7 and: if the can is too fullwill bri about a slight overflowing of; the same. The pad avels in acounter-clockwise direction as edin Fig.1, and the can moves from leftto right. Therefore, the pad will come down into the can for a momentand move along with it and then he lifted from the can.

In order to maintain the pad in ahorizontalpositiomi havev provided thecrank arm 32 which has been referred to above. The rotating support 30is eccentrically set relatively to the gear wheellft'. The stud 38engaging the crank arm and moving in the same timing as thesupportingshaft 9 for the pad will keep the pad in horizontal position. The

stud maintains the crank 32in a vertical posi-.

tion throughout the entire rotation of the sup port tor the pad, andthis, of course, keeps thepad in horizontal position. I

From the above it Will be apparent that I have provided a device whereinthe means for moving the pad is a positively operating means, operatingintiming with the means which cause the bodily travel of the which thepad cooperates.

' It will also'be apparent that I haveprocans with.

vided a positively operating membermovin-g tion, becomes thedriving'ineans for the support for the pad, and the only additionalmeans for drivingand maintaining the pad in horizontal position is thecross shaft, which transmits the motion of' the disk or gear wheel whichmaintains the pad horizontal to the traveling support which moves thepad bodily in its circular path'of travel;

It is obvious that minor changes in the details of construction maybe-made without departing from tlie'spirit of the inventionas set forth.in the appended claims. 7

Having thus described my invention, What I desire to cover by'UnitedStates Letters Patent, is: r r
